I have more system calls which might be cleaner if I send them as a list. Do I break it into a separate item for each argument? Any need for quotes? Here are the other system calls. They do actually work as they are but I would like to learn how to use the system call the "right" way so to speak.

When putting a smiley right before a closing parenthesis, do you:

Use two parentheses: (Like this: :) )
Use one parenthesis: (Like this: :)
Reverse direction of the smiley: (Like this: (: )
Use angle/square brackets instead of parentheses
Use C-style commenting to set the smiley off from the closing parenthesis
Make the smiley a dunce: (:>
I disapprove of emoticons
